The terms you are looking to have defined have varying definitions. I will give you the ones most commonly used and give you some places to look for additional information. According to the website for the televsion show Antique Roadshow, "As Michael points out, the word "antique" generally refers to an older object valued because of its aesthetic or historical significance." The definition of the word antique, since in some ways it carries a relative meaning [what is antique in a younger culture like the US may be considered not antique in an older culture like the UK]. In the US, the definition was set somewhat by the US Customs officials who needed to determine what imports should be classified as antiques. Their conclusions were as follows: "Antiques, they concluded, were objects that pre-dated the mass production of objects in the 1830s. Since the defining moment went back about 100 years, the office defined an antique as something made over 100 years ago. Duty was collected on objects younger than the century-old divider, and it still is." Generally, while antiques need to be a certain number of years old to be thought of as antique, vintage has more to do with the relative age of the item, in terms of the age of the class of things to which it belongs. The word vintage comes to us from wineries and includes quality in its definition "Characterized by excellence, maturity, and enduring appeal" so while an antique could be anything that was particularly old [and, one would assume, saleable] items that were vintage would be presumed to be of high quality.
